i Specific-ation of Letters Patent. i" Patllilted Illy 29,1919.

To allg/whom t may concern.'

Be 1t known that I, WALTER T. GLENN, a citizen of the United States, residing at Pine Bluff, in the county ofJeferson and` State of Arkansas, have invented certain new and useful Improvements in Mountings for Slasher-Saws, of which the following is a specification.

My invention relates to a mounting for slasher saws.

The objects of the invention are, first, to provide the collars, between which the saw is clamped, with outwardly beveled edges next to the saws to allow the saws to bend laterally over beveled edges, instead of over straight edges and so prevent breaking of the saws at the eye, as is now commonly the case. Secondly, to provide removable and interchangeable bevel edged collars of different diameters, the larger collars serving to clamp saws having breaks at the eyes and so renderingY them capable of re-use.

These objects I accomplish by the construction shown in the accompanying drawing, in which: Y

Figure 1 is a plan of a Slasher sawing machine.

Fig. 2 is a sectional side elevation.

Fig. 3 is a longitudinal section through a pair of the clamping collars with a saw clamped in place. Y

Fig. 4 is a perspective of the mounting separated, and

Fig. 5 shows a pair of the larger collars secured in place on the hubs in lieu of the smaller collars of Figs. 3 and 4.

A, A designate sprocket wheels mounted on parallel front and rear shafts D, D, and over these sprockets pass the endless conveyer chains C, C, having fingers or projections to carry the slabs or lumber toward the slasher saws I. The upper horizontal runs of the conveyer chains C, C travel over a horizontal table or supporting floor J.

E, E are shaft hangers depending from any overhead support, notl shown, and provided at their lower ends with journal boxes B, in which the saw shaft K is journaled. The saw shaft K is in several longitudinal sections provided at their abutting ends with hubs K having transverse bolt holes lc, 7c through which the clamping bolts k, c are passed for clamping the hubs and the saws I together. These hubs K are provided with annular shoulders cz around g, g lie next'to the opposite sides of the saws I, I. rI he abutting ends of the sections of shaft K are provided, concentric with the hubs K', with a socket los and tenon 764 respectively to assist in holding the shaft sections in proper alinement.

kThe rings or collars G, G in Fig. 5 are considerably larger than the collars G, and are interchangeable therewith. Y

The rings or collars G, G are employed with new saws or saws having unbroken eyes, while the larger heavier rings or collars G are employed with saws which are broken in thev eye, and I find that by the use of these larger beveled collars G saws which were cast aside as useless may be used with perfect safety and with good working results. Y

By beveling the collar edges neXt to the sides of the saws the saws are allowed to bend laterally over a curved or inclined surface instead of over a rectangular edge as in the commonly used form of clamping col-v lar, which latter angular edge causes the saw to break at the eye and so become useless. The advantages of my beveled collars have been proven in practice both as to new saws and saws broken at the eye. The rough work done by Slasher saws necessitates a free lateral bend at the collar edge not desired in types of circular saws employed in finer work.

What I claim is:

2. A mounting for Slasher saws comprising clamping collars to engage opposite sides of the saws; said collars being beveled outwardly on their adjacent faces to allow the saw to bend laterally over the bevels without breakingat the eye.

2. A mounting forslasher saws comprising clamping collars formed of inner hubs and outer removable collars or rings beveled outwardly on their adjacent saw-engaging faces to allow the saws to bend laterally over the bevels without breaking at theeye.

3. A mounting for Slasher saws comprising hubs and interchangeable collars of diff ferent diameters mounted thereon; the smaller collars for unbroken saws and the larger collars for saws broken at the eye;
